The USPS needs 180,000 new delivery vehicles, automakers gearing up to bid

Winning the New York City Taxi of Tomorrow tender was a huge prize for Nissan, even though the company is still working through the process of claiming its prize. The United States Postal Service has begun the process to take bids for a new delivery vehicle to replace the all-too-familiar Grumman Long Life Vehicle, and that will be a much larger plum for the automaker who wins it, perhaps worth more than six billion dollars. The Grumman LLV is an aluminum body covering a Chevrolet S-10 pickup chassis and General Motors' Iron Duke four-cylinder engine. The USPS bought them from 1987 to 1994, and the 163,000 of them still in service are a monumental drain on postal resources: they get roughly ten miles to the gallon instead of the quoted 16 mpg, drink up more than $530 million in fuel each year, and their constant repair needs like the balky sliding door and leaky windshields have led the service to increase the annual maintenance budget from $100 million to $500 million. A seat belt is about as modern as it gets for safety technology, and the USPS says that assuming things stay the same, it can't afford to run them beyond 2017. Last year it put out two triage requests for proposals seeking 10,000 new chassis and drivetrains for the Grumman and 10,000 new vehicles. The LLV is also too small for the modern mail system in which package delivery is growing and letter delivery is declining. The service says it doesn't have a fixed idea of the ideal "next-generation delivery vehicles," but it listed a number of requirements in its initial request and is open to any proposal. Carriers have some suggestions, though, saying they want better cupholders, sun visors that they can stuff letters behind, a driver's compartment free of slits that can swallow mail, and a backup camera. The request for information sent to automakers pegs the tender at 180,000 vehicles that would cost between $25,000 and $35,000 apiece, and it will hold a conference on February 18 to answer questions about the contract. GM is the only domestic maker to avow an interest, while Ford and Fiat-Chrysler have remained cagey. Yet with a possible $6.3 billion up for grabs and some new vans for sale that would be advertised on every block in the country, we have a feeling everyone will be listening closely come February 18. We also have a feeling the LeMons series is going to be flooded with Grummans come 2017. News Source: Wall Street Journal, Automotive News - sub.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.

2016 Chevrolet Malibu Hybrid Quick Spin [w/video]

If a Chevy Volt is like a hybrid that prefers its electric motor, then the new Malibu hybrid is like a Volt you never have to plug in. That's partly because you can't plug it in, but more because the Volt and the gas-electric Malibu share a lot of major components. Since we happen to like the newly refined Volt, that's good news for the larger family sedan. The shared parts include the blended braking system, A/C compressor, the auxiliary power module, and most of the hybrid transaxle (what you might call a fancy electro-transmission). In the Malibu, the electric motors use neodymium magnets for efficiency and power, while the Volt has weaker ferrite magnets to reduce drag, and the Volt also gets an extra clutch to lock out the engine. The two use different batteries, with their size, power capabilities, and chemistry suited to the task for each vehicle. Unlike most of the midsized sedan leaders, the Malibu has never had a full hybrid option. For a few years in the last generation, Chevy offered the Malibu Eco with a version of GM's eAssist mild-hybrid system, which featured a small motor-generator in place of an alternator hooked up to a bigger battery that could harvest energy during deceleration and add some back in when you hit the throttle; it also brought engine stop-start functionality to save a little more fuel. But it saved only a little fuel, so eAssist was nixed in favor of a more efficient four-cylinder with a standalone stop-start system. Driving Notes Mode switches between gas and electric are just as smooth as in the Volt. No shudder or weirdness in the throttle. It drives as much like a gas-only car as any midsized hybrid does. The blended braking system is also noticeably well sorted. There's no deadness in the pedal, no touchiness, and no artificial, wooden feeling when you step through the regen portion of its travel. There's nothing abrupt or jarring about any of the experience, and the Malibu's baked-in quietness helps to deal with noise from the somewhat coarse 1.8-liter gas engine. Engine startup and shutdown are noisy from outside, but much less noticeable from within. The 2016 Malibu is larger yet lighter. The hybrid weighs about 125 pounds more than a comparably equipped 1.5T. You don't notice the extra weight, but there is some space eaten out of the trunk by the battery.
